If A is a symmetric matrix, which relation is correct? (Level 6 practice)
यदि A symmetric matrix है, तो सही relation कौन-सा है? (लेवल 6 अभ्यास)
Show answer and explanation
Correct Answer
B. A^T = A
ExplanationStep 1: Recall the definition of a symmetric matrix. Step 2: For a symmetric matrix, the transpose is the same matrix, so A^T = A. Step 3: Symmetric means entries match across the main diagonal.
Step 1: Symmetric matrix की definition याद करें। Step 2: Symmetric matrix में transpose लेने पर matrix वही रहती है, इसलिए A^T = A। Step 3: Symmetric का मतलब main diagonal के आर-पार समान entries।
